Research Overview

Kahalalide F

Kahalalide F was investigated in multiple preclinical and early clinical cancer studies because of its unusual membrane-disrupting and anti-tumor effects. Development highlighted the promise and limits of marine depsipeptides as oncology leads.

RgIA

Scientific studies show RgIA can strongly inhibit alpha9alpha10 nicotinic signaling with high selectivity compared with many other nAChR ligands. It is widely used to probe peripheral sensory pathways and inflammation-linked pain mechanisms.
